I'm on my way to bed, so screencaps will have to wait until the morning, but off the top of my head then one with the King and Queen chesspieces (like my image - but maybe with 'River' and 'Doctor'?). And an animated one which switches between River just standing there and the live Queen, crackling. And maybe one with River and Rose (when Rose is all Bad Wolf-y) and saying 'I want you safe!'
